the 'script' only starts the jar of the server, the main server is start via java. If you want to modify how the server is start the you need to write a custom Launcher which is not supported and not recommended
I have implemented a custom biome, but am not sure how to change the surface of it.
In the past, I used a surfacebuilder to have red sand as my top layer, but I'm not sure how to do this in 1.18.
Currently, I am looking at Mixins in SurfaceRuleData (I think this is how Fabric does it).
Unfortunately, this doesn't work well with Forge Registry items.
How should I go about changing the surface of my biome?
